Nature answers to mind in physical correspondences. The planetary system
is fashioned after a circle. Life itself springs from a spherule of
forces. The perfection of an idea, or the completeness of a conception
may be expressed by a circle. The elements of Science, Astronomy,
Geology, and Natural History, are pictorially represented in this
manner. How appropriately and logically can a fragment of natural
history, this epitome of all nature and science--_the mind_--be
illustrated by a simple circle! Every element must act and react, and be
equal and opposite. Thus may the existence of the opposing energies and
functions of each faculty be equally represented. The contrast aids us
in understanding their ultimate tendencies, and enables us to correctly
value and define their nature. Faculties of kindred qualities may be
grouped together, and their antagonisms represented in the opposite arc
of the circle. Let us employ a circle to represent mind. The conception
of the abstract quality of _good_, requires contrast with one of a
converse nature, _bad_, (see Fig. 69). Opposite faculties may be
portrayed in the same manner. The functions of the cerebrum and spinal
system may be symbolically represented as those of the highest and
lowest organs, thus giving rise to the positive and negative extremes of
feeling. The writer conceives of no other way in which the widely
contrasted facts of human experience can be so perfectly symbolized.
_Good_ (Fig. 69) may represent moral faculties, and _bad_, their
opposites. Undoubtedly, nature is not so arbitrary in her arrangements
as we are in shadowing forth our imperfect conceptions, yet is not this
a decided improvement in determining cerebral faculties and their
relations? We observe how scholars and philosophers confound the noblest
and most exalted emotions with the animal propensities instead of
distinguishing between them. "_The emotions are a department of the
feelings, formed by the intervention of intellectual processes. Several
of them are so characteristic that they can be known only by individual
experiences; as Wonder, Fear, Love, Anger_." See Logic: Deductive and
Inductive, by Alexander Bain, LL. D., page 508, (1874).

This is not an exceptional, but a common example of classifying Love,
the highest and purest of the emotions, with Anger, an anim
